Privacy Policy

1. Data we collect

• Your champion / opponent / lane choices: Processed to compute the recommendation. These choices are not linked to your identity and are not stored in a profile belonging to you.
• Account information: There is currently no membership system; we don't collect personal data such as name, email or password.
• Technical logs: For the healthy operation of the Service and to fix errors, standard server-side access records (request time, error message, etc.) may be kept. These are not used to identify you personally.

2. Game client integration (local data)

The Game Mode and live-advice features read the local interfaces of the League of Legends client running on your computer (Live Client Data API and LCU): the enemy's items, your gold, game time, and so on. This data is used to update the recommendations. When you use the rune-writing feature, the computed rune page is written to your local game client — never to our servers.

Where this data is processed. If you run the site on your own computer, everything stays on your device. On the hosted site the reading is done by the optional desktop helper, and to interpret the readings your browser sends them to our server: champion identifiers, item identifiers, your gold and the game time. Nothing else is sent — no account name, no summoner name, no match history. These readings are used only to compute that one answer; they are not written to a database and are not linked to your identity. If you don't install the helper, none of this is collected and the site works exactly the same, you just pick the champions by hand.

3. Cookies

We use as few cookies as possible:

• Essential: your language choice (dil) and your cookie/ad decision (riza). These simply remember how you configured the site; they are not used to track you and are not shared with anyone.
• Advertising (optional): set only if you explicitly accept them — see the next section.

Champion and item images are loaded from Riot's Data Dragon content network.

4. Advertising

To keep LoL Duel free, the Service may display ads through Google AdSense. The first time you visit, you are asked whether you accept cookies for personalized advertising:

• If you accept: Google and its partners may use cookies and similar technologies to show ads tailored to your interests. That processing is governed by Google's own policy, which you can read at policies.google.com/technologies/ads.
• If you decline ("Essential only"): ads are served in non-personalized mode. Non-personalized ads still use limited data (such as approximate location and the general content of the page) for frequency capping and fraud prevention, but not an interest profile built about you.

Declining restricts nothing. Every feature of the Service works identically either way. You can change or withdraw your decision at any time using the "Cookies and ads" link in the footer.

We do not pass your champion/opponent selections or the local data read from your game client to advertisers.

5. Sharing of data

We don't sell your personal data or share it with third parties for marketing. If legally required, necessary information may be provided to the competent authorities.

6. Your rights

Since there is no account system, you don't have a stored personal profile. When membership is added, you'll be able to exercise your rights to access, correct and delete your data as explained on this page.

To exercise these rights, or to ask anything about how your data is handled, write to destek@lolduel.com.

7. Changes

This policy may be updated; the current version is always published on this page with the date at the top.
